Class CLogViewEvent

class CLogViewEvent : public CLogView;

Description

A view on the event log.

The events included in the view are defined using a filter that specifies the constraints that all events in the view must satisfy. Filters are specified using one or more CLogFilter objects.

Derivation

• CBase - Base class for all classes to be instantiated on the heap
• CActive - The core class of the active object abstraction
• CLogActive - Common active object behaviour
• CLogView - Navigates a view on the log database
• CLogViewEvent - A view on the event log

IMPORT_C ~CLogViewEvent();

Description

Frees all resources owned by the object prior to its destruction. In particular, any outstanding asynchronous request is cancelled

IMPORT_C TBool SetFilterL(const CLogFilterList &aFilterList, TRequestStatus &aStatus);

Description

Initialises or refreshes the event view defined by the set of specified filters.

The view can only be used after the request completes successfully.

Parameters

const CLogFilterList &aFilterList The set of filters. TRequestStatus &aStatus The request status. On request completion, contains:KErrNone, if the view has been successfully initialised or refreshed;one of the other system wide error codes, otherwise.

Return value

TBool ETrue, if the function has successfully issued the asynchronous request. EFalse, if there are no events in the view.

IMPORT_C TBool SetFilterL(const CLogFilter &aFilter, TRequestStatus &aStatus);

Description

Initialises or refreshes the event view defined by the specified filter.

The view can only be used after the request completes successfully.

Parameters

const CLogFilter &aFilter The filter. TRequestStatus &aStatus The request status. On request completion, contains:KErrNone, if the view has been successfully initialised or refreshed;one of the other system wide error codes, otherwise.

Return value

TBool ETrue, if the function has successfully issued the asynchronous request. EFalse, if there are no events in the view.

IMPORT_C TBool SetFilterParseFilterByFilterL(const CLogFilterList &aFilterList, TRequestStatus &aStatus);

Description

Parameters

const CLogFilterList &aFilterList TRequestStatus &aStatus

Return value

TBool
